DRAWER-GUIDE.'

SPEGFCATION forming part of Letters Patent No. 742,132, dated October20, 1903.

Application filed January Z6. 1903.` Serial No. 140,475. (No model.)

To all whom, t mayV concern:

Be it known that I, JOHN SCHAAD, a citizen of the United States,residing at Knoxville, in the county of Knox and State of Tennessee,have invented a new and useful Improvement in Drawer-Guides,of which thefollowing is a specification, reference being had to the accompanyingdrawings.

-The object of myimprovement is to provide the drawers of bureaus,desks, and similar pieces of furniture with antifriction devices forpreventing the binding of the drawers while being opened or closed. Itis the purpose of said devices to prevent the drawer from turninglaterally'out of parallel with the space in which the drawerfnormallyrests and also to prevent the rear upper portion from binding when thedrawer has been par-` tially opened and the front part of the drawerbears downward and the rear portion is raised, the drawer restingpivotally upon the front rail.

My invention is specially designed to aiford simple and economical meansfor forming said guides. i

The present invention is animprovement upon the construction describedin Letters Patent of the United States No. 710,523, granted to meOctober 7, 1902.

In the accompanying drawings, Figure 1 is a vertical transverse sectionthrough a drawer embodying my improvement. Fig. 2 is an enlargedfragmentary rear elevation of the drawer shown in Fig. 1. Fig.` 3 is asection on the line 33 of Fig. 2. Fig. 4 is a rear elevation,.and Fig. 5is a plan, of a modification in which the guide-rollers are secured toablock and the block is secured to the rear face of the rear wall of thedrawer.

Referring first to Figs. 1, 2, and 3, A is the drawer. B B are thehorizontal front rails located above and below the drawer-com partment.C is one-of the horizontal end rails upon which the drawer rests. D Dare back rails, and D D are panels filling the-spaces between the backrails D. Said rails D and panels D together form the rear wall of thedrawer-compartment. Obviously said rear wall may be formed in anysuitable manner, or it may be incomplete or altogether omitted,according to the nature of the article of furniture.

A is the rear wall of the drawer. v The upper edge of this is preferablylower than the upper edge of the front wall A2. At its mid- .dle therear wall A' has a transverse vertical recess or notch a cut into its ucredere of suitable width and depth to receive the vertical roller E,which is suitably journaled, as

upper face of the rear wall of the drawer and against or nearly againstthe lower face of the guide-rail F. Located directly over said rollerYEis a horizontal guide-rail F, secured in any suitable manner, as by theattachment of its ends to the adjacent front and back rails. The loweredge of said guide-rail a1- most touches said roller and is adapted toreceive contact from the latter when the drawer is being pulled out ortilted upward at the rear.

On each side of the guide-rail Fa horizontal roller G is mounted uponthe upper edge of the rear wall of the drawer, a suitable vertical postor axle G extending centrally through each of said rollers. Said rollersare placed so near the adjacent faces of said guide-rail as to causeengagement between Said rollers and said faces when the drawer shiftslaterally to a slight extent. Thus the usual binding of the drawer atits ends when moved out of parallel by moving oneend in or out inadvance of the other end is prevented. The lateral Inovementof thedrawer is prevented by said rollers, and, furthermore, binding on theguide-railis prevented by the ready rotation of V the roller G, which,is brought into contact with said guide-rail. The attachment of saidguide-rail is easily made by cutting it of proper length to extendacross the space between-.the front and back rails. rollers is simplyand economically accomplished. The notch a may be readily cut Theattachment of said antifrictionout of one board or simultaneously cutout of a number of boards clamped together.

By placing the axle E against or into the vertical face of the rear wallof the drawer instead of into recesses cut down through the upper faceof the drawer, as described in my said Letters Patent, the labor islessened and the entire upper face of the drawer-wall is left clear andfree for the application of the horizontal rollers G, and the axle E maybe made of any desired length without intertering with the verticalposts or axles G, which support the two horizontal rollers G, and it isunnecessary to lill recesses in the upper face of the rear .Wall of thedrawer preparatory to attaching therollers G. It will be observed thatunder this construction the guide-rail F maybe narrowed as much asdesired and the rollers G brought correspondingly near to each other.

In Figs. 4 and 5 a block A3 is secured to the rear face ot the rear wallA oi"4 the drawer, the upper edge of said block being iiush with theupper edge of said wall, and the rollers E and G are secured to saidblock precisely as they are secured directly to said wall in Figs. l, 2,and 3. Said block A3 may be secured to said wall by screws a3 or in anysuitable manner. These blocks A3 may be made separately from the drawersand have the rollers attached by theuse of special machines and appliedto the drawers after the latter are otherwise completed. The block A3 isto be regarded as a part of the Wall A' of the drawer after said blockhas been secured to said wall. Said blocks may be ot Wood or metal andmay be varied in form.

I claim as my invention- I. The combination of a drawer, the rear wallof which has a transverse notch in its upper portion, a vertical rollerlocated in said notch and having its axle secured to one of the verticalfaces of said Wall, two horizontal rollers secured to the upper face ofsaid wall, one at either side of said vertical roller, and a guide-rail.

2. The combination ot' a drawer comprising a block applied to the rearwall of said drawer so as to constitute a part of said wall, said blockhaving a transverse notch in its upper portion, a vertical rollerlocated in said notch and having its axle secured to one of the verticalfaces of said block at a proper elevation to bring the upper portion ofsaid roller approximately into line with the upper face of said block,two horizontal rollers secured to the upper face of said wall, one ateither side of said vertical roller, and a guide-rail.

In testimony whereof I have signed my name, in presence of twowitnesses, this 12th day of January,` 1903.

JOHN SCIIAAD.
